shared: fix OgmiosLucidProvider scriptRef extraction (Ogmios v6 shape)

Browse Source 
ogmiosUtxoToLucidUtxo expected `o.script` to be a hex string, but
Ogmios v6 returns it as `{ language: "plutus:v3", cbor: "<hex>" }`
(or "native"). The typeof === "string" guard never matched, so
scriptRef was always null on returned UTxOs — making
.readFrom([refUtxo]) silently produce a tx with no script witness
and the supplier reject the resulting Claim with 503.

Wired ogmiosScriptToLucidScript() to translate the Ogmios shape into
the lucid-evolution shape across all four script languages.

Verified end-to-end: tmp-repro now reports
"scriptRef: present type=PlutusV3 cborlen=6884" against the published
ref UTxO (250928de…#0).
